2022年10月12日 · Armature reaction is the effect of magnetic flux produced by the armature current on the distribution of flux under the main poles of a DC generator. The armature flux …

The effect due to which the armature reaction reduces the total flux is known as the demagnetizing effect. The resultant flux is distorted. The direction of the magnetic neutral axis …

2021年1月17日 · The opposition of armature flux on the main field flux is called armature reaction. This armature reaction has two undesirable effects, either it weakens (reduces) the main field …

2024年2月27日 · In essence armature reaction alters the distribution of the main field around the air gap periphery and induces demagnetization within the machine. The demagnetizing impact …

2015年5月23日 · Since armature demagnetising ampere-turns are neutralized by adding extra ampere-turns to the main field winding, it is essential to calculate their number. But before …

Armature Reaction: The effect of magnetic field set up by armature current on the distribution of flux under main poles of a generator. The armature magnetic field has two effects: (i) It …

2022年12月25日 · Armature reaction is the effect of a magnetic field set up by armature current on the distribution of flux under the main poles of a generator. The armature magnetic field has …

This opposition of armature flux on the main field flux is known as armature reaction. The armature reaction has two undesirable effects. The first is it reduces the main field flux called …

2012年2月24日 · The cross magnetizing armature reaction effect is mainly caused by armature conductors which are located under the pole arc. At high loads, this effect of armature reaction …

As a consequence in presence of saturation, armature reaction apart from being cross-magnetizing also causes a net reduction in flux/pole, a demagnetizing effect. However, no …
